So no one should be wearing a tuxedo during the day. It’s also a bit odd to have a black tie event that is outside. With that said, American weddings seem to do this fairly often, strangely. But it’s called eveningwear for a reason. Cool so I got that out. If you’ve seen maybe Dr. No or Casablanca, you might remember an ivory or cream dinner jacket? Dr. No took place in Jamaica and Cassablanca obviously for Casablanca. Those jackets are typically made of breathier fabrics, have less canvassing and have a double vent for exactly this reason. They’re appropriate to wear in extremely hot places. Currently that applies to every place imaginable. The trick to the cream or ivory dinner jacket is to try it on and remember that you don’t want to look like a waiter. For this reason I avoid ivory. Cream is more traditional. Shawl collar is popular. Sometimes a turn up cuff will make it look less waitery. Ultimately the idea is you have your tuxedo and if it’s extremely hot, you just toss on the cream dinner jacket. So if you’re going in this direction, I’d avoid anything else that’s out for he ordinary for black tie. No velvet. Answer from Chodepoker1 on reddit.com
